Abstract
Polycarbonate obtained by solid state polycondensation (SSP) crystallizes in an orthorhombic configuration with a = 12.1 Å, b= 10.1 Å, and c = 22.0 Å. Its morphology is of non-spherulitic lamellar type, while that of melt or solution crystallized commercial polycarbonate is distinctly spherulitic. These changes in crystalline structure and morphology can be explained, in the present case, on the basis of restricted mobility of the chains and the crystal growth in an extended chain configuration during the SSP step.
